When the probe of the electroscope is brought near a charge, free charges in the electroscope rod are either attracted to or repelled from the probe. This leaves a net charge at the other end of the rod (since the electroscope as a whole is electrically neutral). Since the other end of the rod is charged, its parts repel each other (since like charges repel). Thus, the gold-leaf indicators spread apart.

Describe how an electroscope works to detect static electricity?
An electroscope can detect static electricity by having a metal plate or rod that easily gains or loses electrons. When there is static electricity present, the electrons will be transferred to the metal, causing the leaves of the electroscope to repel each other due to the like charges. This repulsion causes the leaves to spread apart, indicating the presence of static electricity.
What is a device used to detect the presence of a static charge?
An electroscope is a device used to detect the presence of a static charge. It works by using two thin metal leaves that separate when a charge is applied, indicating the presence of static electricity.
What does electroscope measure?
An electroscope is an early scientific instrument that is used to detect the presence and magnitude of electric charge on a body. It was the first electrical measuring instrument. The first electroscope, a pivoted needle called the versorium, was invented by British physician William Gilbert around 1600.[1] The pith-ball electroscope and the gold-leaf electroscope are two classical types of electroscope that are still used in physics education to demonstrate the principles of electrostatics. A type of electroscope is also used in the quartz fiber radiation dosimeter.Electroscopes detect electric charge by the motion of a test object due to the Coulomb electrostatic force. The electric potential or voltage of an object equals its charge divided by its capacitance, so electroscopes can be regarded as crude voltmeters. The accumulation of enough charge to detect with an electroscope requires hundreds or thousands of volts, so electroscopes are only used with high voltage sources such as static electricity and electrostatic machines. Electroscopes generally give only a rough, qualitative indication of the magnitude of the charge; an instrument that measures charge quantitatively is called an electrometer.Source : Wikipedia
Principle of electroscope and types of electroscope?
An electroscope is a device used to detect the presence of electric charges. It works on the principle of charge induction, where like charges repel each other causing a leaf or needle to diverge. The two main types of electroscopes are the gold-leaf electroscope, which uses thin gold leaves, and the pith-ball electroscope, which uses lightweight balls of plant material.

What is the function of an electroscope?
Well it can be used for radiation, etc. the main function is to demonstrate various electrostatic phenomena, e.g., conduction and induction of electric charges. it can also be used to see if something is charged which should make the two fine aluminum blades repel.

What is the function of electroscope?
An electroscope is used to detect the presence of electric charge, either positive or negative. It works by using the principle of electrostatic induction to indicate the presence of charge on an object through the divergence of a pair of thin metal leaves that are suspended in the apparatus.
How does a static strap works?
A static strap works by grounding the static electricity on an object to prevent the buildup of charge. The strap typically contains conductive materials that provide a path for the static charge to dissipate safely to the ground. This helps protect electronic devices and equipment from damage caused by electrostatic discharge.
How does electronscope woks to defect static electricity?
An electronscope works by using a fine nozzle to release a stream of electrons that neutralizes any excess static electric charge on an object. The electrons ionize the air molecules around the object, allowing the static electricity to dissipate harmlessly.
Mention the principle on which an electroscope is based upon?
An electroscope works based on the principle of electric charge repulsion. When a charged object is brought close to the electroscope, the free electrons within the electroscope move toward or away from the charged object, causing the gold leaves in the electroscope to diverge, indicating the presence of a charge.
What would change about the way an electroscope worked if its metal knob was replaced with a plastic one?
Replacing the metal knob of an electroscope with a plastic one would not significantly affect its functionality. The electroscope works by detecting the presence of electric charge on the metal knob, and plastic material does not conduct electricity. The only difference may be that plastic is an insulator and cannot hold a charge like metal, so the electroscope may not be as sensitive in detecting the presence of electric charge.
What are an anti-static wristband?
Anti-static wrist bands or anklets help ground a person and divert static electricity. This is useful when a person works in demolition. A spark can ignite plastic explosives, and the anti-static wrist bands greatly reduce the likelihood that static electricity would detonate the materials prematurely.
